[Herpes virus in cell cultures of the hematopoietic organs of Hamadrymas baboons with hemoblastosis].

Five transplantable suspension lymphblastoid cell cultures from haematopoietic organs of baboons with malignant lymphoma were obtained, designated as KMPG-1, SPG-1, 2, 3, 4. The cells of these suspension cultures contain HVP virus belonging to herpes-type according to morphological (electron-microscopic) investigation, but differing from infectious viruses of this group and closely related to Epstein-Barr virus as evidenced by its characteristics. In conformity with the preliminary data the isolated HVP virus is oncogenic for M. arctoides monkeys.
